Ported shotgun chokes are essentially choke tubes that have been modified with holes or ports along the side of the tube. These ports serve to redirect gases and reduce the overall recoil and muzzle jump experienced when firing a shotgun. By allowing gases to escape through the ports, ported chokes help to stabilize the barrel and reduce the amount of felt recoil that the shooter experiences. This can be particularly beneficial for shooters who are sensitive to recoil or looking to improve their accuracy and control.
